' ViG-W illusireiing my ina single cylindrical gin -opening at one s ide t on relefres to iuiprcweinent in n "mines for treating ruhher and other heavy plastic material in which a casing is employed with e charging-opening in the top 0'? the casing. a verticallyqnovehle closure for said casing, and one or more rotors in the said casing. Some means must he prorided for conveniently raising the closure. and the object of this invention is 10 provide a. simple arrun ement of parts whereby the closure may be conveniently ruised or lowered, and the invention consis'ts in the construction as Will he hereinafter described and particularly recited in ihe claim.

in carrying out my invention, as shown in Fig. l of the drawings, I employ a stationrs cry or non-tilting casing 5 having two cylindricui .:-h:uul;1ers (5 and 7. respectively couiuiuiu z rotors 8 and 9. The top of the cuse charging-opening 10 for which I provide a vertically-movable closure 11, while bottom of the casing has a dis- (lIZLlgQ-OPOIIlDQ 18 for which I provide a. horizontally-movahle closure 19. The said charging-opening 10 opens upwardly into the lower end of an upstanding housing or county of New Haven. and Siate e broken sectional View illustrating I neck 20, providing a. hearing for the closure 11 and furnished as one side with an ofisetting hopper 21. For the operation of the said closure I employ e long flireaded. stem 12 extending upward through the said neck and also through a, chambered head 1 mounted directly upon the upper end thereof and receiving a wheeldike nut 13 held against vertical displacement by it. The said nut- 13 carries an annular Worm-gear 15 meshed into by c Wormshar't l6 driven, from any convenient source of power, in one direc sion i011 lifiing the closure 11 shove the hoetoin of the hopper 21. end in the opposite direction for permitting it he descend into posiiion close the chargingopening 10.

instead of arranging the charging-opening centrally of e double cylindrical casing, it may he arranged over one of the charm here 7, as shown in Fig. 2 of the drawings; or, in case of a single'cylindricel chamber 17 is employed, as shown in Fig. 3 of the drawings, the charging-opening may he arranged centrally thereof. or an. one side there of, as shown in Fig. l of the drawing I claim: In e machine of the class specified, the combination With a stationary casing hawmg is, charging-opening in its top and a discharge-opening in its bottom, of a rotor,

a horizontally-movable closure for the said discharge opening, a vertically-movable closure for the said charging opening, a neck rising from the casing and providing a housing for the said vertically-movable closure, 2. be per discharging. into the said neck, a charm cred heed mounted upon the upper end of the said neck, 2. threaded stem connected at its lower end with the vertically-movable closure and extending upward through the said neck and head, a nut located Within the said head, held against displacement thereby and receiving the threaded upper end oi -the said stern, an annular worm-gear upon the periphery of the said nut, and a worm-shaft meshing inio the said annular worm-gear.

In testimony whereof, I have signed this specification in the presence of two subscril ing witnesses. I
